^Simply put: people have different musical tastes
I'm a relatively old fan (I began with Vogue), but I think My Story has yet to be surpassed. I think Guilty is almost as weak an album as A Song for XX (her weakest), and that Memorial Address lacks album cohesion for me to consider it as anything but a side project.
It is quite a challenge to learn to appreciate A Song for XX. The only song I can listen to from that album in its original form is A Song for XX. Everything else is just so... "idol debut from the 90s!"
